Extension methods for raw pointers

Required methods

Provided methods

unsafe fn add(self, i: usize) -> Self

unsafe fn sub(self, i: usize) -> Self

unsafe fn pre_inc(&mut self) -> Self

Increment the pointer by 1, and return its new value.

Equivalent to the C idiom ++ptr.

unsafe fn post_inc(&mut self) -> Self

Increment the pointer by 1, but return its old value.

Equivalent to the C idiom ptr++.

unsafe fn pre_dec(&mut self) -> Self

Decrement the pointer by 1, and return its new value.

Equivalent to the C idiom --ptr.

unsafe fn post_dec(&mut self) -> Self

Decrement the pointer by 1, but return its old value.

Equivalent to the C idiom ptr--.

unsafe fn inc(&mut self)

Increment by 1

unsafe fn dec(&mut self)

Decrement by 1

unsafe fn stride_offset(self, s: isize, index: usize) -> Self

Offset the pointer by s multiplied by index.

Implementations on Foreign Types

impl<T> PointerExt for NonNull<T>[src]

NonNull<T> supports the same offsetting methods under the same safety constraints as the other raw pointer implementations.

There is no difference - both when offsetting *mut T and NonNull<T>, the offset is only well defined if we remain inside the same object or one-past the end, and we can never land in a null pointer while obeying those rules.
